To all whom it may concern: 7

Be it known that I, JACQUES HUBER, merchant, a citizen of the SwissConfederation, residing at Streitgasse No. 7, Basel, Switzerland, haveinvented certain new and useful Improvements in Nut-Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures marked thereon, whichform a part of this specification.

The invention relates to a wrench adapted for use as a nut-wrench and itconsists in the peculiar construction and combination of deviceshereinafter described and claimed.

One object of my invention is to provide a wrench having a series oftumblers mounted on a handle to form an adjustable companion jaw to suitnuts of diiferent sizes.

A further object of my invention is to provide a wrench composed ofelements which may be readily assembled or disassembled.

In the accompanying drawings: Figure 1 is a side elevation of a wrenchembodying my improvement. Fig. 2 is a section on line A-B of Fig. 1 withthe tumblers out of the jaws. Fig. 3 is a section on line AB of Fig. 1with the tumblers between the jaws.

The improved wrench comprises a handle 1 and two fixed jaws 16, 17. Inthe space 2 between the jaws 16, 17 a series of tumblers 5 are arranged(Figs. 1 and 3). Each of the tumblers 5 consists of a fiat piece of ironwhich is journaled on a pin 4 the latter being mounted in lugs 3, 3 ofthe handle. Between the tumblers 5 and one of the lugs 3 a coiled spring6 is arranged which presses the tumblers 5 against the jaw 16. Thehandle 1 is further provided with a recess 7 into which the tumblers 5maybe placed when out of use. To the bottom of said re- Specification ofLetters Patent.

Serial No. 763,335.

cess 7 a plate spring 9 is fixed by means of a screw 8. The spring 9 isbent off at 10 and rests against the side walls 13 of the tumblers 5when the same are out of use and against the side walls 12 when thetumblers are between the jaws 16, 17 thus securing the tumblers againstaccidental displacement. At the side of the recess 7 a lug 15 isprovided Which protects the tumblers 5 when out of use against blows,etc. The width of the space 2 may be varied according to the size of thenuts by turning more or fewer tumblers between the jaws.

It will be understood that various changes in the form, proportion andthe minor details of construction may be resorted to without departingfrom the spirit or sacrificing any of the advantages of this invention.

Having described my invention what I claim is:

1. A wrench comprising in combination a handle, two jaws on said handle,a series of tumblers rotatably mounted on a pin on said handle, a coiledspring around said pin to hold the tumblers together, a spring adaptedto hold said tumblers when in or out of use, a lug for protecting thetumblers which are not used substantiallyas described.

2. A wrench comprising in combination a handle, two jaws on said handle,a series of tumblers rotatably mounted on a pin of said handle, a coiledspring around said pin to hold the tumblers together, a blade springarranged in a recess of said handle, a bent off portion on said bladespring adapted to press against the hind ends of all the tumblers, a lugfor protecting the tumblers substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
